nfsd changes for 3.4

[J. Bruce Fields]

The following nfsd-related changes are available from the for-3.4 branch
at:

  git://linux-nfs.org/~bfields/linux.git for-3.4

Highlights:
	- Benny Halevy and Tigran Mkrtchyan implemented some more 4.1
	  features, moving us closer to a complete 4.1 implementation.  
	- Bernd Schubert fixed a long-standing problem with readdir
	  cookies on ext2/3/4.
	- Jeff Layton performed a long-overdue overhaul of the server
	  reboot recovery code which will allow us to deprecate the
	  current code (a rather unusual user of the vfs), and give us
	  some needed flexibility for further improvements.
	- Like the client, we now support numeric uid's and gid's in the
	  auth_sys case, allowing easier upgrades from NFSv2/v3 to v4.x.

Plus miscellaneous bugfixes and cleanup.

Thanks to everyone!

There are also some delegation fixes waiting on vfs review that I
suppose will have to wait for 3.5.  With that done I think we'll finally
turn off the "EXPERIMENTAL" dependency for v4 (though that's mostly
symbolic as it's been on by default in distro's for a while).

And the list of 4.1 todo's should be achievable for 3.5 as well:

though we may still want a bit more experience with it before turning it
on by default.
